Description Dmitry Burstein 2009-12-13 04:47:27 UTC
Summary:

SELinux is preventing /usr/libexec/mysqld "unlink" access on
squeezebox-mysql.sock.

Detailed Description:

SELinux denied access requested by mysqld. It is not expected that this access
is required by mysqld and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2009-12-14 12:06:29 UTC
You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
